In the case of azoospermia, the probability of obtaining usable sperm is low, and the possibility of using donor sperm may be considered. In this case, sperm have no way of exiting the testicles. Moreover, the distinction between living round spermatids, to be used in ROSI, and dead round spermatids, to be discarded, needs specific methods and skills, not required in the case of ICSI where sperm cell viability can be easily evaluated on the basis of sperm motility in most cases. Her sheer brilliance and professionalism shone bright! You are leaving our website.

Such is the case with Intracytoplasmic Sperm Injection (ICSI). A Belgian physician pioneered the ICSI process in and first reported his incredible successes at the annual American Fertility Society (now known as the American Society for Reproductive Medicine) scientific conference. ICSI is very similar to conventional IVF in that gametes (eggs and sperm) are collected from each partner. The difference between the two procedures is the method of achieving fertilisation. In conventional IVF, the eggs and sperm are mixed together in a dish and the sperm fertilises the egg ‘naturally’. Intracytoplasmic Sperm Injection: ICSI Home / Infertility / Intracytoplasmic Sperm Injection: ICSI Intracytoplasmic sperm injection (ICSI) involves the direct injection of sperm into eggs obtained from in vitro fertilization (IVF).

This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a icsi intracytoplasmic sperm injection uterus. With this method acrosome reaction is skipped. However, the steps to be followed before and after insemination are the same. This is due to the fact that in IVF icsi intracytoplasmic sperm injection reaction has to take place and thousands of sperm cells have to be involved. Once fertilized, the egg is transformed into a proembryo and it has to be transferred to the uterus to continue its development.
